The Flowcup may be worn for 6-10 hours at a time, or changed 2-4 times per day depending on how heavy your flow is. Using the Flowcup during your period will help you to understand your body's individual rhythm during this time and you will soon know how many times you will need to change it during the day/night.

A step-by-step instruction leaflet is included with your Flow cup. For additional information and support please see How to Use Your Flowcup and feel free to Ask Mama Roux if you have any further questions.


Rinse and/or wipe clean between each insertion during your period. In-between cycles wash well, sterilise, and leave to dry completely before storing in a breathable cotton bag. Please see Flowcup Care for more detailed information on how to look after your Flowcup.
